In production activity, starting manufacturing of a new product involves taking a particular risk. Therefore, the need arises for investigating the rational basis for starting such projects. This process should begin from the verification of the opportunities of reaching the expected effects of...

The coincidence of speculative crisis within more developing economies has become more and more an emphasizing phenomenon, being analyzed by specialty literature. The way of inflationary tensions taken over the Thailand’s baht currency in 1997, which has lead fast to theoretical tensions over...

A mathematical economic model of measuring a worker’s potential and cost-of-living is proposed. Two aspects of the problem of untimely loss of an average statistical demographic element are considered: loss of profit for the regional business system as a whole and the lost value for the...

The aim of this work is to develop and evaluate a mathematical model for the process of storing hydrogen obtained from hydroelectricity via electrolysis, for use as an energetic vector in rural areas of Venezuela. Following an exhaustive bibliographical review of the subject, pressurized...

Seawater-source heat pump systems (SWHP) are recognized to be outstanding heating, cooling and water heating systems. A large number of SWHP systems have been used in residential and commercial buildings in coastal areas due to the attractive advantages of high efficiency and environmental...

A wind turbine blade generally has complex structures including several layers of composite materials with shear webs. It is essential but also inherently difficult to accurately and rapidly calculate the cross-sectional properties of a complex composite blade for the structural dynamics and...

For some locations both global and diffuse solar radiation are measured. However, for many locations, only global is measured, or inferred from satellite data. For modelling solar energy applications, the amount of radiation on a tilted surface is needed. Since only the direct component on a...

This paper develops a novel mixed integer nonlinear programming model for the intra-cell layout design of dynamic cellular manufacturing systems. In dynamic environment, the product mix and part demand are varying during a multi-period planning horizon. As a result, the cell configuration for...

Presentation of enterprise potentials in the form of potential functions that express dependence of the size of potentials on parameters of the state of an enterprise and external environment of its functioning requires development of a qualitatively new methodologies and methodical approaches...

This paper highlights an evaluation of the potential level and nature of sustainability for large-scale photovoltaic (PV) solar power plants. This was achieved by applying a mathematical model of sustainability to the results of a qualitative-based environmental impact evaluation of the...
